Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reverse rotation preventing mechanism of a fishing type spinning reel or a closed face reel, which is a silent type reverse rotation preventing mechanism which does not make a sound in a fishing line winding direction (forward rotation direction). .

[0002]

2. Description of the Related Art A silent type reverse rotation preventing mechanism of a drive shaft that rotates in conjunction with a handlebar is disclosed, for example, in Japanese Utility Model Laid-Open No. 1-103363. This is a reverse rotation prevention gear attached so as to rotate integrally with a drive shaft that rotates the rotor with the rotation of the handle, a locking claw engageable with the gear,
A control body that is rotatably mounted on the drive shaft and that can prevent the engagement between the gear and the locking pawl by rotating, and a friction body that is friction-wound around the drive shaft and expands in diameter during normal rotation A silent type reverse rotation prevention mechanism having a spring that can rotate the control body by locking one end to the control body so as to reduce the diameter at the time of reverse rotation. Since there is no contact, the winding operation can be performed quietly without generating sound.

[0003]

However, in the case of an operation in which the engagement of the locking claw with the gear is released by the stopper release lever to enable reverse rotation, and the fishing line is actively drawn out while the handle is reversely rotated, the rotation of the handle is prevented. Resistance occurs and smooth feeding is not possible. This is because the diameter of the spring is reduced at the time of reverse rotation, thereby increasing the frictional force.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a silent type reverse rotation prevention mechanism for a fishing reel capable of performing a smooth feeding operation when a fishing line is actively fed by reverse rotation.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention is directed to a reverse rotation preventing ratchet mounted so as to rotate integrally with a drive shaft for rotating a rotor as a handle rotates. A locking claw that is constantly urged to engage with the vehicle and rotatably supported on the reel body, a spring frictionally wound around the drive shaft, and a fishing line winding of the drive shaft A control body that rotates with respect to the drive shaft along with the frictional rotation of the spring when rotating in the direction to separate the locking claw from the reverse rotation prevention claw wheel; A silent type reverse rotation preventing mechanism having a restricting portion that can be brought into contact and restricts the rotation thereof, and a cam that can be operated by an external lever and that can act on the locking claw and detach from the reverse rotation preventing hook wheel. And the spring is Both ends are extended outwardly of,
The present invention provides a silent type reverse rotation prevention mechanism for a fishing reel, wherein the two extending portions are configured to sandwich a part of the control body.

[0006]

[Function] Since both extension portions of the spring hold a part of the control body and are not free ends, each extension is caused by the frictional force accompanying the rotation of the drive shaft in both forward and reverse rotations. Deformation in the direction in which the provided portions approach each other can be prevented, the spring does not contract in diameter, and the frictional force during each rotation including during reverse rotation does not increase.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a partially broken side view of a fishing spinning reel according to the present invention, and FIG. 2 and FIG.
Is an enlarged view of the main part. Referring to these figures,
The drive shaft 14 rotates with the rotation of the handle 10. The rotation of the drive shaft 14 causes the rotor 12 to rotate.
A spool shaft 18 for moving the spool 20 back and forth is inserted through the drive shaft 14.

On the other hand, a pivot 24 is projected from an upper portion of the reel body 16 rotatably supporting the drive shaft 14, and a locking claw 26 is rotatably attached to the pivot 24. . An urging spring 25 that constantly urges clockwise in FIG. 2 is attached to the locking claw 26. A stopper cam 33 penetrates through the reel body 16, and a lever 32 for operating the stopper cam 33 is attached to the outside.

A reverse rotation preventing wheel 22 is provided at a position where it can be engaged with the locking claw 26 and is mounted on the outer periphery of the drive shaft 14 so as to rotate together with a cylindrical portion 22A. A ring-shaped spring 30 is wound around the cylindrical portion 22A of the reverse rotation preventing wheel 22. The spring 30 generates a spring force in a direction to reduce the diameter. Therefore, when the drive shaft 14 rotates, the spring 30 also tries to rotate in the same direction due to frictional force.

Further, both ends of the spring 30 are extended outward, and extended portions 30A and 30B are formed to face each other. On the other hand, a control body 28 is rotatably mounted on the outer periphery of the cylindrical portion 22A. An upper portion of the control body 28 is sandwiched between the extending portions 30A and 30B, and the locking claw 2 is rotated by the rotation of the control body 28.
6 against the urging force of the urging spring 25,
An engagement portion 28A that can be separated from the projection 2 is protruded.

Therefore, if the drive shaft 14 is rotated by rotating the handle 10, the spring 30 and the control body 28 also rotate in the same direction.
The three pins 34 </ b> A and 34 </ b> B protrude from the reel body 16. Each of the engaging portions 28A of the control body 28 is
4A or 34B, and its rotation is regulated. Accordingly, the spring 30 and the control body 28 are stationary with respect to the rotation of the cylindrical portion 22A of the reverse rotation preventing pawl 22 that rotates integrally with the drive shaft 14, and friction occurs between the spring 30 and the cylindrical portion 22A.

In FIG. 2, the handle 10 is rotated in the reverse direction to rotate the drive shaft 14 in the direction of the arrow, but since the position of the operation lever 32 is at the reverse rotation preventing position (solid line), the locking claw 26 rotates in the reverse direction. It is engaged with the prevention pawl 22 and cannot be reversed. In this state, the engaging portion 28A of the control body 28
The extension 30A side of the spring 30 is in contact with the pin 34A.

In this state, when the handle 10 is rotated in the normal rotation direction, which is the winding direction of the fishing line, the drive shaft 14 rotates in the direction of the arrow shown in FIG. With this rotation, the spring 30 and the control body 28 rotate in the same direction, and the control body engaging portion 28
A stops when the extension portion 30B side of A comes into contact with another pin 34B. Further, the locking claw 26 is separated from the reverse rotation preventing wheel 22 by the upper surface of the engagement portion 28A. Therefore, at the time of the forward rotation, no sound is generated due to the contact between the locking claw 26 and the reverse rotation preventing ratchet wheel 22, and the fishing line can be gently wound.

FIG. 5 shows a state in which the handle 10 is rotated in the reverse direction with the position of the operation lever 32 switched to the reversible position 32 'of the two-dot chain line shown in FIG. The locking claw 26 is rotated by the stopper cam 33 to prevent the reverse rotation of the hook wheel 2.
2 is maintained. When the handle 10 is reversely rotated in the separated state, that is, in the state in which reverse rotation is possible, the drive shaft 14 can rotate in the direction of the arrow in FIG. 5 and the fishing line can be forcibly drawn out.

In this case, the spring 30 is rotated in the same direction together with the control body 28 by a frictional force acting in the same reverse rotation direction.
The engagement portion 28A of the control body 28 comes into contact with the pin 34A and the rotation stops. A friction force acting in the same direction acts on the spring 30 sandwiching the cylindrical portion 22A of the reverse rotation preventing ratchet 22, and the extending portion 30B tends to move in the diameter reducing direction that presses the engaging portion 28A. However, the diameter cannot be reduced due to the presence of the engagement portion 28A. Further, the extension portion 30A tends to deform away from the engagement portion 28A in a direction to expand. Therefore, the diameter of the spring 30 does not contract even if it is expanded, and the frictional force between the spring 30 and the cylindrical portion 22A that rotates integrally with the drive shaft 14 due to the reverse rotation does not increase, and the fishing line is sent out by the reverse rotation. Is performed smoothly.

The fact that the diameter of the spring 30 does not shrink and the frictional force does not increase is the same as in the case of the normal rotation in FIG. Therefore,
The resistance to the rotation of the handle at the time of forward rotation or reverse rotation due to the presence of the spring 30 is small.

FIGS. 6 and 7 show a second embodiment according to the present invention. The difference from the first embodiment is that a holding portion 28B 'is formed in addition to the engagement portion 28A' of the control body 28 ', and both sides of the holding portion 28B' are extended portions 30A 'and 30A of the spring 30'.
B '. As the drive shaft 14 rotates, the spring 30 ′ and the control body 28 ′ rotate.
When B 'comes into contact with the pin 34A' or 34B ', the spring 3
0 'and the rotation of the control body 28' are stopped. Also in the case of this example, the extended portions 30A 'and 30B' of the spring 30 'sandwich the sandwiching portion 28B' and the distance therebetween does not become narrow. Therefore, as in the case of the first embodiment, the resistance of the spring to the rotation of the handle during forward rotation and reverse rotation is small.

[0018]

As is apparent from the above description, according to the present invention, the fishing line is wound in a silent state when the handle is normally rotated, so that the handle is engaged with the anti-reverse hook to prevent the handle from reversing. A part of the control body, which acts to separate the locking claw from the reverse rotation preventing wheel, is held between the two extension portions of the spring. When the spring is deformed due to the friction of the spring, the distance between the two extending portions of the spring does not decrease, so that the frictional force does not increase, and the fishing line is actively fed by reversing. Thus, it is possible to provide a silent type reverse rotation prevention mechanism for a fishing reel capable of performing a smooth feeding operation.
